I'm no expert, but as I understand it there are several aspects to good topology:

1. You have to be very careful with the wiring: use "star" grounding, don't run signal wires to close together, cross them at right angles instead of paralleling them, etc.

2. The circuit itself has to be correct: things that need to be in the opamp's feedback loop need to be in there, things that should be outside need to be. Deciding which is which is a matter of experience.

3. Use lots of decoupling caps between gain stages, and between the power supply and opamps/buffers. Also, the caps should be as close as possible to the parts they decouple.

By way of counterexample, a random layout on cheap protoboard with haphazard wiring and a minimal circuit (i.e. very few decoupling caps, etc.) will be very likely to cause high-speed opamps to oscillate.

Again, this is all hearsay. I don't speak from experience on this matter.
